1. Viessmann wall-hung boiler maintenance cycles and projects
| Maintenance items | Recommendation cycle | Operational points |
|---|---|---|
| exterior cleaning | 1 time per month | Wipe the body with a soft cloth and avoid using corrosive cleaners |
| Burner inspection | 1 time per year | Clean carbon deposits and ensure uniform flame |
| water pressure monitoring | 1 time a week | Maintain 1-1.5Bar, if it is below 0.5Bar, add water |
| System blowdown | Once every 2 years | Remove impurities from pipes to prevent clogging |
| Professional maintenance | Once every 3 years | Contact after-sales service to inspect heat exchangers, seals, etc. |
2. Daily maintenance precautions
1.Antifreeze protection: When not in use for a long time in winter, the power supply needs to be kept on to prevent the water tank from freezing and cracking.
2.water quality management: In areas with hard water, it is recommended to install a water softener to reduce scale deposition.

3. Answers to users’ high-frequency questions
| question | solution |
|---|---|
| Wall mounted boiler is noisy | Check whether the fan has accumulated dust or whether the water pump has not exhausted all the air. |
| Decreased heating efficiency | Clean the dust on the surface of the heat exchanger and check the gas pressure |
| Frequent flameout | It may be that the gas pressure is insufficient or the flue gas emissions are not smooth. |
4. Professional in-depth maintenance steps
1.Shutdown and power outage: Close the gas valve, cut off the power supply, and wait for the equipment to cool down.
2.Internal cleaning: Use special tools to clean the combustion chamber to avoid damaging the refractory materials.
3.Seal detection: Focus on checking the pipeline interface and replacing the aging sealing ring.
4.System debugging: After maintenance, the CO₂ concentration needs to be recalibrated to ensure sufficient combustion.
5. Recommended list of maintenance tools
| Tool name | Purpose |
|---|---|
| Electronic pressure gauge | Accurately measure water pressure |
| Nylon brush set | Clean heat exchanger fins |
| Gas leak detector | Safety inspection essential |
